A HIIT and interval timer that stays out of your way. No ads. No tracking. Nothing interrupts your workout. WHY INTERVALFLOW โ€ข No ads, ever โ€” not a banner, not a video, not between rounds. Your countdown is never covered and your audio is never cut. โ€ข No tracking โ€” no analytics, no advertising identifier, no account. Your workouts stay on your device. โ€ข Live Activity and Dynamic Island โ€” the current phase, the countdown, and the round stay on your Lock Screen. Check mid-set without unlocking. BUILT FOR REAL WORKOUTS โ€ข Ready-made presets: Tabata, HIIT 40/20, EMOM, boxing rounds, and multi-set circuits. โ€ข Custom builder: prepare, work, rest, rounds, sets, rest between sets, and cooldown โ€” to the second. โ€ข A countdown you can read across the room, with each phase in its own colour: work, rest, get ready, cooldown. โ€ข Sound, haptics, and voice cues, so you can keep your eyes off the screen and on the set. IT KEEPS THE RECORD โ€ข Every finished session is logged on its own โ€” time, rounds, and an estimate of calories. โ€ข A daily streak and a weekly count, for the weeks when motivation needs a number. Made for HIIT, Tabata, cross-training, boxing, running intervals, stretching, EMOM, and circuits โ€” at the gym or on your living room floor. Open it, tap a preset, and start. That is the whole app.
